Both kinds of knowledge are brought together - observations for the traditional naturalist and rigorous measurements and interpretations for modern scientists, integrated into a single, readable account. This edition provides a comprehensive summary of the extensive advances over the last 15 years.

Using the seasonal roads (passable only from spring to fall) of Steuben County, New York to establish setting, the author, a literary naturalist, contemplates the meaning of "place" as she walks the back roads, bringing nature to life.

Environmental conditions change considerably in the course of 24 h with respect to abiotic factors and intra- and interspecific interactions. These changes result in limited time windows of opportunity for animal activities and, hence, the question of when to do what is subject to fitness maximisation. This volume gives a current overview of theoretical considerations and empirical findings of activity patterns in small mammals, a group in which the energetic and ecological constraints are particularly severe and the diversity of activity patterns is particularly high. Following a comparative ecological approach, for the first time activity timing is consequently treated in terms of behavioural and evolutionary ecology, providing the conceptual framework for chronoecology as a new subdiscipline within behavioural ecology. An extensive Appendix gives an introduction to methods of activity modelling and to tools for statistical pattern analysis.

A comprehensive treatment of the fierce little predators: physical description, life cycle and span, evolution, hunting and reproduction behavior, population dynamics, the impact on their prey, diseases, and their relation to humans (mostly as pests, i.e. competitors). The color plates are informative, but the line drawing are marvelous. Annotation copyrighted by Book News, Inc., Portland, OR

The impact of sterilisation and culling control of stoat (Mustela erminea) populations was evaluated using models of increasing complexity. The first was a simple logistic model with continuous births and deaths; the second included a more realistic birth pulse rather than continuous births; and the third included a birth pulse and age structure. For beech forest (Nothofagus spp.) habitats, the birth pulse models distinguished between mast, crash and normal years, each year having a different intrinsic rate of increase, rm, which was parameterised from trap-catch indices. The second model best predicted the large variation in stoat abundance observed in beech forest. Using this model, little difference was predicted in the proportional reduction of stoat density under culling or sterilisation control. Under continuous control, sterilisation was slightly more effective at reducing peak (summer) stoat density; however under pulsed control, culling was marginally more effective than sterilisation. Control of either kind was much more effective against populations in non-beech forests than against those in beech forests, essentially because of the former population's lower rm value. The second birth pulse model was also used to predict the likely dynamics of canine distemper virus (CDV) in stoat populations. CDV was not predicted to persist as an endemic disease in New Zealand stoat populations. This was primarily due to the birth pulse structure which precluded the continuous recruitment of susceptible individuals required to maintain the disease within a host population.
